Preheat your oven to 425°F (220°C). Melt 2 tablespoons of unsalted butter in a heavy-bottomed, oven-safe non-stick skillet over low heat, coating the bottom of the pan.

Peel and slice 2.5 pounds of high-starch potatoes into 1/8-inch thick slices, ensuring uniformity for even cooking.

Layer the potato slices in a circular pattern in the skillet, overlapping slightly and seasoning with salt and pepper between layers.

Cut the remaining butter into small pieces and scatter them over the layered potatoes.

Cook on stovetop over medium heat for about 4 minutes. Cover and transfer to the oven for 25 minutes.

After 25 minutes, uncover and bake for an additional 20 minutes, checking for golden-brown color.

Shake the skillet to loosen the layers and invert onto a serving platter to present the Pommes Anna.
